STILL FOR REFINING PETROLEUM.

SPECIFICATION formingpart of Letters Patent No. 269,382, dated December 19, 1882, i applicati@ nieu May 1o, issn. (No mout-.1.)

To all whom it may concern:

Beit known that I, ASA A'. BUsH,ot` Titusville, in the county of Crawford and State of Pennsylvania, have invented a new and useful Improvement in Stills for Refining Petroleum and the manner ot' setting the same, of which the following is a specification.

My invention relates principally to those stills known as cheese-box stills, or those having a round,lat bottom with upright sides, the object being to increase the surface eX- posed to the lire by increasing the length of tlues through which the products of combustion must pass before escaping to the chimney, to reduce the number of tires, and thereby economize in the use of fuel. This I attain by the inode of construction and setting illustrated in the accompanying drawings, in whch- Figure l is a plan of the bottom of the iuterior ot' the still; Fig. 2, a plan ofthe walls, furnaces, and filles under the still on line a b in Fig. 3; Fig. 3, a vertical section of the still and setting on line c d in Fig. 2; Fig. 4, a ver tical section of one-fourth of the bottom of the still and setting, on line c j' in Figs. l and 2, as it would appear if extended to a plane suriace; and Fig. 5, a vertical cross-section of the same on line o h in Fig. .3, (each quadrant of the still and sett ing beingconstructed precisely alike.)

In the different drawings the same parts are indicated bythe same letters. In Figs. l and 2 one quadrant only and in Fig. 3 one side only is lettered, the other parts being precisely alike.

A is the still; B, brick .wall inclosing the same and supporting it around the outside; C, walls of turret supporting the still in the center; D D, radial walls from the turret to the outside wall, B. These are built solid from the foundation to the bottom of the still; E E E, concentric partition-walls; H, a depressed ring in the bottom of the stilly around next the outside. Lying in this depression are the direct and return fines F and G, opening at each end into the fire-space under the still, as hereinafter described. These ues are preferably about eighteen inches in diameter, and the depression H of the same depth, and from three to three and one-half times the width.

I is a grate or furnace, inclosed in brick, and discharging the products of combustion into the direct ue F, the returniue G opening into the tire-space outside the walls of the furnace I. K is a furnace, the heat from which passes directly against the bottom of the still under the depressed ring H; L L L L, dues connected by the openings M M M at alternate ends of the partition-walls E E E, the first opening being at the opposite end from the furnace K and the opening from the returntlue G. N N are arches dividing the turret into the separate chambers O and l). R is an opening from the Bue L into the chamber O, and S an opening from the chamber 0 to the chamber l. T is a tlue leading from the chamber P downward through the chamber Oto the smoke-flue V, which leads to the chimney or stack W.

The operation is as follows: When the still A is first filled the tires are started in the furnace I, the heat and products of combustion passing (as indicated by the arrows) through the direct and return iiues F and G and the several iiues L and openings M and R into the chamber O in the turret; thence through the opening S-direct-ly against the bottom ot' the still; from there through the fluesTand smokellue V to the stack V, and escaping. This continuesvuntil the quantity ot' oil in the still is so reduced that thereis danger ot' burning the vapor by the extreme heat in the direct and return lines F and Gr. The tires are then transferred from the furnace I to the furnace K, when the beat and products ot' combustion pass direct into the flue L, and from thence take the same course as before, except that they do not pass through the i'lues F and G, and the distillation is complet-cd. As a matter of course, when the furnace I- is in use the door of the furnace K must be kept tightly closed, and vice versa.

I claim as my inventionl. A still for retning petroleum, consisting of the body A, provided with the annular depressed ring H, said depression being provided with two or more sets of direct and return lues, F and G, constructed substantially as described, and for the purposes herein set forth.

2. The combination, with the still A and its exterior supporting-Walls, of two or more re- 3. The combination, with the still A, conboxes, the concentric interior walls, E E E, structed :is described, and its exterior snphaving openings MM M, forming the series of' porting- Walls, of' two or more pairs of fireues L L L, the tire-box and the nes L L L boxes, I and K, for alternate use, connected 5 being connected, as set forth, the Wall C formwith the lines L L L,substantia-lly as described.
